If you remove the disc and later put it back in the EDGE will remember the AR for that disc and render it properly (4:3). EDGE does provide independent AR settings for SD and HD but has to be told how to scale SD, since there's no standard AR; it can be 16:9 or 4:3. Setting my BD player to Auto output solves this, since the AR is set in the player that way. I guess you could try this procedure with a 2:35 disc and see what happens.
The ideal would be some auto AR control that includes 2:35, I guess. Are there any other VPs out there that do? I don't know, since I don't keep up with things that much.
I don't entirely understand what you mean... Perhaps I should explain what I said a bit more:
My satellite box (Sky HD) is set up so it doesn't upscale anything. It sends 16:9 SD material over HDMI with a flag to indicate that it's an anamorphic widescreen image. It sends 4:3 material without the flag. Most 16:9 displays (including my projector) will recognise the flag and switch the anamorphic display mode on or off as appropriate so the correct aspect ratio is always used (e.g. when flipping between tv stations).
I believe DVD players also send these anamorphic flags over HDMI (and analogue connections sometimes), but obviously if they are set to upscale to HD, they need to recognise the flag internally.
The scaler needs to upscale SD signals to 1080p which is always 16:9, so if you don't want to turn the anamorphic display mode on or off manually when you're channel surfing (and I expect most CI customers wouldn't want to do that), you need the scaler to recognise the widescreen flag so that it knows when to stretch SD to 16:9 and when to display it pillarboxed. My understanding is that the VP50 can do this but the feature was disabled on the Edge.
The 2.35:1 thing is a separate issue. It would be great if material carried a 2.35 flag but I don't think BDs do at the moment and I'm sure DVDs never will. It would also be great if equipment could somehow recognise 2.35 material (by 'looking' for the black bars), but I don't know of any products that can do that at the moment. For now, you have to manually press a button to tell your system when you're viewing 2.35 material.
If you have a 16:9 screen you might want to have a 2.35 button that zooms in the right amount to get rid of the black bars by cutting off the sides of the picture. Some might dismiss that as heresy, but I'm sure a lot of CI customers might want the facility to do this.
Or if you want to use a 2.35 projection screen with a 16:9 projector and no anamorphic lens, you need a scaler that will pillar box and letterbox 16:9 and 4:3 material (so that any active area of the picture is kept between the area that would appear as 'black bars' when viewing a 2.35 movie on a 16:9 screen).
Again, my understanding is that the VP50 can be set up for either of these 2.35 applications but the Edge can't.
It would obviously be good if these features were enabled on the Duo, especially if it's intended to be effectively an Edge for custom installers.
Some on this forum have been questioning whether we really need scalers in the age of HD and especially BD, so it seems to me that it would be wise for scaler manufacturers to concentrate on providing advanced automation features for custom installers, as well as on improving picture quality.
